Christian Schneider commented on CXF-6737:

Can you post the relevant snippets of your configs, service interface and impl?

Without specifying the wsdl url, it doesn't work since apparently the method argument names
don't match (arg0 vs actual parameter name, as explained in CXF-897), so I added the wsdl
url. Now service methods that have a return value seem to work ok, but those with void return
type do not.
> Further investigation suggests that the issue might be in ReflectionServiceFactoryBean:
initializeWSDLOperation prints out a warning (no method for op) instead of binding the operation,
because initializeClassInfo returns false, because initializeParameter called with the return
type (near the bottom of initializeClassInfo) returns false, since o.getOutput().getMessagePart/getMessagePartByIndex
return null (since there are no parts - the method can throw an exception, for which the output
message exists, but there is no actual return type).
> A quick test in the debugger shows that if I manipulate the flow manually (e.g. execute
the if caluse in initializeWSDLOperation after initializeClassInfo returns) then the method
invocation works ok.
> I am not familiar with the inner workings of WSDL or these classes, so I'm not sure what
is the correct place to apply a fix.
